WebApr 13, 2024 · In eukaryotes, dynamins and dynamin-related proteins (DRPs) are high–molecular weight GTPases responsible for mechanochemical fission of organelles or membranes. Of the six DRP subfamilies in Arabidopsis thaliana, AtDRP1 and AtDRP2 family members serve as endocytic accessory proteins in clathrin-mediated endocytosis. Most … WebDynamin partners bind to the PRD and may either stimulate dynamin’s GTPase activity or target dynamin to the plasma membrane. Purified dynamin readily self-assembles into rings or spirals.
